For the PCA, t-SNE and OC-SVM methods, we used the implementations available from the scikit-learn Python library [1]}. All computations were performed on the Nvidia GTX2080 graphic card. The size of the input images was 256x256 px and the batch size of the CAEs was set to five for training. Scripts used for the experiments were written in Python 3.6 and the Tensorflow 2.4.1 library was used to train the CAEs.
